Publication number: 20110232244Abstract: Z-filter media pack arrangements and methods for providing them are described. The preferred arrangements have a cured-in-place jacket around an outside of a coiled z-filter media combination. The preferred cured-in-place jacket is a mold-in-place overmold which includes, integral therein, a housing seal arrangement. Preferably a cured-in-place center core is used, most preferably one that has opposite concave ends with seal arrangements configured to seal a lead end portion of the coiled z-filter media combination.Type: ApplicationFiled: April 4, 2011Publication date: September 29, 2011Applicant: Donaldson Company, Inc.Inventors: KEVIN J.

Publication number: 20080216654Abstract: Fluted filter media includes filter material having a plurality of flutes formed therein having alternating ends of adjacent flutes closed to force fluid through filter material. A first embodiment of the filter media includes tapered flutes which have the open ends of the flutes larger in cross-section than the closed flutes, wherein the upstream open flutes converge toward the downstream end and the upstream closed end flutes diverge toward the downstream end. A second embodiment includes filter media which is asymmetric formed with dissimilar upstream and downstream flute cross-sections with larger flute openings to the upstream side of the filter. A third embodiment includes filter media with an upstream edge crushed to improve flow at the upstream edge. A fourth embodiment includes filter media with the upstream sealing material recessed from the upstream edge for reducing effects from blockages at the upstream edge of the filter.Type: ApplicationFiled: February 11, 2008Publication date: September 11, 2008Applicant: Donaldson Company, Inc.Inventors: Wayne M. Wagner, Gary R. Gillingham, Joseph C. Tokar, Daniel T. Risch, Jim C. Rothman, Fred H. Wahlquist, Bernard A. Matthys, Gregory L. Reichter, Stephen W. Sabelko, Bryan D. Patten
